The Super Duty trucks are built on a separate platform from the smaller F-150. Bigger, stronger and more robust, they are meant to perform feats of which the F-150 isn't capable. The maximum GVWR for the F-150 is 7,700 pounds, the F-250 Super Duty can handle 8,800 pounds, whereas the F-350 Super Duty starts at 9,900 pounds and ranges up to 11,500 pounds. The main mission here is towing and hauling. To provide the necessary grunt, Ford offers three different engines. The gasoline engines are a Triton 5.4-liter V8 and a 6.8-liter V10. The V8 generates 255 horsepower at 4,500 rpm and 350 pound-feet of torque at 2,500 rpm. The V10 generates 310 horsepower at 4,250 rpm and 425 lb-ft of torque at 3,250 rpm. A 7.3-liter turbodiesel V8 is also available, and it makes 250 horsepower at 2,600 rpm and a dominating 505 lb-ft of torque at 1,600 rpm. All of these engines can be equipped with an optional automatic transmission. The F-350 can tow up to 12,500 pounds of conventional trailer when properly equipped and can even wrestle a 14,400-pound fifth-wheel trailer. (Link to full review)
